Title: Method and system for multi-channel collision-free submission of gps data, control device, and terminal
Inventor: DU RUI
IPC: H04W74/04
Filed: 2019-05-29
Abstract: A method and system for multi-channel collision-free submission of GPS data, a control device, and a terminal. The method comprises the following steps: a control device receives an original activation signaling transmitted when a dispatch station is issuing a subscription, and, modifies the original activation signaling according to a preset rule so that terminals having a same subscription cycle are in one group; the control device issues a first pull-up signaling to the terminals at a slot adjacent to a control channel to instruct the terminals to hop to a designated GPS service channel on the basis of the first pull-up signaling; and when the terminals having a same subscription cycle have hopped to the designated GPS service channel, the control device issues a second pull-up signaling to the terminals to allow the terminals to submit GPS data on the basis of the second pull-up signaling. This allows the implementation of ensuring, when making GPS data submissions, that the GPS data submissions are strictly spaced apart to avoid collision, allows the implementation of dynamic expansion of GPS resources, allows a user to achieve an expanded GPS capacity limit by means of expanding carrier frequencies, obviates the need to occupy additional control channels, and increases the utilization rate of channel resources.
